Stihl Incorporated USA is a well-know manufacturer of outdoor power equipment such as chainsaws, leaf blowers, industrial demolition saws, edgers and hedge trimmers. If you have acquired a Stihl HS45 model hedge trimmer and wish to start it for the first time, it is a fairly straightforward task. Before you begin, be sure to fuel the unit according to the manufacturer's directions.


Step 1

Slide the blade lock lever forward toward the front handle.

Step 2

Press the stop switch into the interlock position.

Step 3

Press down on the throttle trigger interlock lever, squeeze the throttle trigger and hold it in that position.

Step 4

Press in the starting throttle lock.

Step 5

Set the choke lever to the cold starting position and press the fuel primer bulb a minimum of five times.


Step 6

Place the unit on the ground and remove the blade scabbard. Be sure that the blade does not make contact with the soil.

Step 7

Grasp the machine firmly with your left hand pressing down on the front handle.

Step 8

Pull the starter handle and rope until you feel it begin to engage. Give the rope a strong swift pull. As the engine starts, gradually slide the starting rope back into the unit so that it will rewind properly.


Step 9

Tap the trigger quickly. This action releases the engine from the full choke position.

Step 10

Allow the engine to warm up for a minute or two before beginning to trim your hedges.
